The One S packs a sweetSATA IIIdrive, but itmaystill be using the SATA II interface of the original Xbox One. You can always add an external hard drive though, thanks Microsoft!

Step 10

The nexttogo is numbertwo: the optical drive—tooeasy! Master Chief is of coursealongfor the ride.

Here we have theartist formally knownas a BD-ROM drive, courtesy of Philips and Lite-On Digital Solutions. The DG-6M5S model found in the Xbox One S is slightly different from theDG-6M1Sfound in the Xbox One, with the biggest upgrade being support forBD-UHD.

We also snag a couple rubber bumpers. These probably help keep the high-speed optical drive from rattling us off our rockers.

Step 11

Now we come to the One S'shat trick(a.k.a. #03)—a smaller, newly-fanless, neatly-integrated power supply. Gone is that dangling anchor of yore.

Welcome to the club, Xbox One.

An external power supply is much easier to replace than an internal one. So lets hope Microsoft did their homework to mitigate that need!

This power supply also accepts 100-240 V inputs, meaning you can take it pretty much anywhere there's a socket. Take that,Xbox One!

The power supply connects with what PC gamers will instantly recognize as a perfectly ordinary,6-pin PCIe connector.

Step 12

Things areheating upin the teardown room, but we can't extract the "Thermal System" just yet. So we lift the whole dang motherboard assembly out of the metal casing.

A springy, X-shaped bracket secures the heat sink to the motherboard—a signature part we've seen in every Xbox since theoriginal 360.

The "X" is a bit fussy and takes some muscle, but some practiced prying with a flathead driver saves the day.

Step 13

With the component countdown nearly complete, it's time to extract part number 01: the thermal system.

Out comes the system's single 120 mm fan—looking much like a PC case fan, but with some sculpting that's unique to the Xbox One's design.

The standard Xbox One had a similarly robust cooling setup, possibly designed to avoid a repeat of the Xbox 360'sbillion dollar problem.

The backup for the One S's biggest fan is an impressive aluminum heat sink and copper heat pipe set.Cool.
